As preferred embodiment, described information indicating module 204 also can be prompted to the driver with the wagon flow congestion status of wagon flow under the vehicle.
The programmed control flow process of above-mentioned energy-conservation driving prompt system is as shown in Figure 4: system begins to start and initialization: microprocessor 203 begins to receive the information that GPS module 202 is gathered, and information comprises: the distance B between junction ahead number information and vehicle and the junction ahead, this highway section Maximum speed limit V
Max Microprocessor 203 is handled the transport information that receives simultaneously, and therefrom extracts the timing information of the affiliated wagon flow of this car; Microprocessor 203 is sent the information that receives to row computing as shown in Figure 5, calculates maximum energy-saving and drives speed.
Travel from south to north as a certain car at a time, the 400 meters arrival in the place ahead are numbered 0007 crossing, and affiliated highway section is unimpeded, and this car is kept straight at this crossing and passed through.Then described ATMS by form and the content about the timing information of the traffic lights at this crossing that described wireless RF transmitter module 1 sends is: [crossing numbering, a1, b1, a2, b2, a3, b3, a4, b4, a5, b5, a6, b6, a7, b7, a8, b8, signal period], for example [0007,0,10,13,27,1,30,50,53,62,1,0,10,13,27,1,30,50,53,62,1,68], the information that certain described ATMS can obtain is not only the information at this crossing, and it can obtain the information at other numbering crossings, quotes the traffic lights timing information at this crossing at this.
The information of obtaining by GPS module 202 is: the crossing be numbered 0007; Arrive the remaining mileage D=400 rice of junction ahead; Vehicle crossing is forwardly kept straight on, thus under the vehicle wagon flow be numbered 7; Highway section Maximum speed limit V

If vehicle in first clearance interval just by the crossing travel speed be: V
1=(400/30+400/50)/2=10.65 meter per second=38.4 kilometer/hour;
If it is interval by the crossing that vehicle is let pass at second, namely pass through the crossing in [a7+68, b7+68] this time period, then travel speed is V
2=(400/ (30+68)+400/ (50+68))/2=3.74 (meter per second)=13.4 kilometer/hour;
If it is interval by the crossing that vehicle is let pass at the 3rd, namely pass through the crossing in [a7+2*68, b7+2*68] this time period, then travel speed is V
3=400/30+68*2+400/50+68*2/2=2.28 (meter per second)=8.2 kilometer/hour,
If it is interval by the crossing that vehicle is let pass at the 4th, namely pass through the crossing in [a7+3*68, b7+3*68] this time period, then travel speed is V
4=400/30+68*3+400/50+68*3/2=1.64 (meter per second)=5.9 kilometer/hour,
By that analogy, V
22=400/30+68*21+400/50+68*21/2=0.273 (meter per second)=0.981 kilometer/hour,
V
22＜Vmin=1 kilometer/hour, stop to calculate.
In the 4th step, relatively obtain V by first comparer 2031
1, V
2V
22In near the economic speed per hour V of vehicle
a=80 kilometers/hour value is V
1=38.4 kilometers/hour;
In the 5th step, determine that theoretic best travel speed value is V
e=38.4 kilometers/hour:
Again by second comparer 2032 V more whether
Min＜V
e＜V
Max, obtain V after meeting above-mentioned condition
e=38.4 kilometers/hour.
In the 6th step, determine to drive strategy:
This highway section congestion level is unimpeded, and described information indicating module 204 can be pointed out by LCDs or Audio Players: " the place ahead is travelled unimpeded, please travels for 38.4 kilometers/hour with speed ".
Above embodiment only is one of embodiment of the present utility model.Protection domain of the present utility model is not limited to embodiment, and any people who is familiar with this technology can understand conversion or the replacement expected in the disclosed technical scope of the present invention, all should be encompassed in of the present invention comprising within the scope.
